Fluid transportation by a sheet of material

Apparatuses and methods are provided for transporting fluid to a sheet of material. Typically, the sheet is immobilized on an upper surface of a support structure. A container holding a fluid is provided along with a conduit having a fluid-conveying lumen that extends from the container to one or more terminal opening facing the lower surface of the sheet. Optionally, a porous medium is placed in fluid communication with the fluid-conveying lumen and in contact with the lower surface of the sheet. The apparatuses and methods provide a variety of interfaces that facilitate controlled fluid transportation from the lumen against gravity for absorption by the sheet.
